Streamline TV by Signia
"I am trying to connect the Streamline TV Bluetooth device between Streamline TV, STB, Pioneer VSX-1020 AV receiver, and Samsung One Connect Box. All have Toslink connections. I can get it working, but not through the different inputs are selected on the receivers. Streamline Tv is for streaming to hearing aids."
Later versions of the Samsung One Connect Box have a Toslink digital optical output. Why don't you drive the Streamline TV from the output of the TV, rather than trying to drive it from the output of the AV receiver?
